Original application filed October 1.8, 19 e i N 7 ,3; D i a d hi l iafi ed Marga This case is a division of my .coepending application SerialNo. 744,313, filed Octoba 1 1. 2 a

This invention relates toa novel and 1mpnoved arm particularly one fromwhich arms may be .cut for use vvithdisplay raq s. It ,is the object .ofthe invention to provide an arm which shall-be strong enough to carrythe heavy loads imposed thereon .and at the same time shall be light inweight, easily made andone which willretainit shape.

vIn the accompanying drawings in which I have shown aseleetedembodimentof this invention: r

Fig. 1 is an elevatien .of a dlsplay rack having an arm construe-ted ofmy novel and iniprouedarm. v d 7 Fig. 2 is an enlarged transversesection ,through the arm ,ofFig. 1.- p v Fig. 3 is anenlarged elevationof the same arm. p i

Fig, dis a section on the line of ,Eig. 2,. drawn .on an enlarged scale,

In Fig. 1 ,thearm 1 is pivoted iat2 to .a hinge ;bar ,3 secured to aWall plate gwhlch in turn is attached to the avalle, or ;other suitablesupport. The outer end of vthe arm is provid t jro l r 6 adapted to keepthe .arm 1 spaced from other, arms ,vv-h ch may be mounted upon .theihinge plate, as s Well known in the art. ,Eaeh arm-ispreferablyprovided with a brace 7 to support it in 'ithe correct posit on, Eas'setforth in my aforesaid co-pending application.

Referring now particularly to Figs. 2 and 3, it will be seen that thearm is made from a single sheet of material, such as sheet metal andcomprises a vertical stem 8 and a head 9, these forming a T-beam. Thestem 8 1s m the form of a U having substantially vertical parallel sides10, these sides being formed by bending the material as at 11. It Wlllbe noted that one of the sides 10 is shorter than the other and as shownin Fig. 2 this side, which is the left one, has its upper end bent at 12at substantially right angles to the vertical portion of the side toform a portion 13 of the horizontally disposed head 9. p

The other side 10 is bent at 14 to form a portion extending insubstantially the same plane as the portion 13, and is then bent onitself at 15, depressed at 16 between the tops of the sides 10 and it isthen carried over the Serial m. 32,611.

From the above it Will be evident that I have provided an arm from whicharms may be cut for use With a display rack, or Which may be used forany other structural purpose for Which it maybe adapted, and which .isextremely light in Weight, at the same time possessing the requisitestrength. F urthermore, my novel and improved arm is very cheaply andvery easily made because, it is possible to manufacture iton a drawbenchinstead of employing a press. Furthermore, it may be easily manufacturedin long pieces, from Which any desired length may be cut. The verticalstem With its tWo parallel sides furnishes a ready means for makingconnections of a piece of arm to other elements. All that is necessaryis to insert a portion of the other element be tween the two sides whichmay then be pressed into engagement therewith, as 6X' emphhed ll'ifilyCO-PGl'lCllHg application.

I am aware that changes in' the form, construction and arrangement ofparts may be made without departing from the spirit and withoutsacrificing the advantages of the 10 invention and I reserve the rightto make all such changes as fairly fall within the scope of thefollowing claims.

I claim:

1. A display rack arm in the form of a T and formed of one piece ofsheet material,

the stem of said T being in the form of a U, the sides of said U beingbent outwardly to form the head of said T, and one of said sides beinglonger than the other and bent upon itself and'overlying the said otherside terial beingin contacting relation with each other.

i 2. A display rack arm comprising a single sheet of material bent intothe form of a T,

the stem of said T'being in the form of a :40 U, one of the sides ofsaid U being longer than the other and each side being bent outwardly atright angles from the U to form the head of theT, the longer of saidsides being folded back upon itself, depressed be- 35 tween the sides ofsaid U, and overlying and folded under the outwardly bent portion ofsaid shorterside. I

3. A display rack arm comprisinga single sheet of material bent into theform'of a T, 40, the stem of said T being in the form of a U, one of thesides of said U being longer than the other and each side being bentoutwardly at'right angles from the. U to form the head of the T, thelonger of said sides being folded back upon itself, depressed betweenthe sides of said U, andoverlying and folded under the outwardly bentportion of' and formed of one piece of sheet-material,

the stem of said T being in the form of a U, the sidesof said U beingbent outwardly to form the head of said T, and one of said sides beinglonger than the other and bent upon itself and overlying the said otherside, said sides being knurled adjacent their edges to prevent relativelongitudinal movement therebetween.

5. A display rack arm in the form of a T and formed of one piece ofsheet material, the stem of said T beingin the form of a U, the sides ofsaid U being bent outwardly to form the head of said T, and one of saidsides being longer than the other and bent upon itself and overlying'thesaid'otherside and folded thereunder, said sides being knurledadjacenttheir edges to prevent relati've longitudinal movement therebetween.

6. A'display rack arm comprising a single sheet of material bent intothe form' of a T,

the stem of said T being in the form of a U, one of the sides of said Ubeing longer than the other and each side being bent outwardly at rightangles from the U to form the head of the T, the longer of said sidesbeing folded back upon itself, depressed between the sides of said U,and" overlying a'nd folded I under the outwardly bent portion of saidshorter side, said sides being knurled adjacent their edges to pre'ventrelative longitudinal movement therebetween.

' 7, An arm for a display rack, comprising i an elongated unitary memberT-shaped in cross section, the stem of thesT being U shaped and the headof said T formed of contacting lateral portions'of said member, and thesaid head having a depression ex tending into the sa-id'stem.
